UNITED STATES PATENT OFFICE.

GEORGE ROERIG. 0E ATLANTA, GEORGIA, .ASSIGNOR TO ATLANTA PAPER COMPANY,

or ATLANTA, GEORGIA, A CORPORATION or GEORGIA.

Be it known that I,.GEoRcE ROEBIG, ,a citizen of the United States,residing at :Atlanta, in the county of Fulton and State of Geor ia, haveinvented certain new and useful Improvements in Collapsible FlexibleBoxes and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements .n flexible boxes, andparticularly with relation to that class of flexible boxes which are so,constructedas to fold fiat and be turned or folded up into properposition when they are to be used as a box.

The primary object of this invention is to provide a box formed from asingle fiat blank, without slits or projections, which can be foldedflat and which can be turned up and the ends and side walls so securedas to form a very rigid structure.

\Vhile the invention not restricted to the exact details and fasteningmeans shown, still for the purpose of disclosure reference is bad to theaccompanying drawings illustrating a practical embodiment of theinvention, and the particular features of novelty will be moreparticularly pointed out in the claim.

fragmentary perspective view of the body portion of the box as itappears when the sides are turned up but just before finally securingthe end and side walls. Fig. 3 is an interior perspective view of onecorner of the body ortion of the box with the side and end wal s firmlysecured together. Fig. 4 is a plan view of a rectangular'blank forforming a rectangular box or box top, the dotted lines showingthepositions of scoring or creasing to enable the side and end walls ofthe box or box top to be turned up,

and Fig. 5 is a detailed View of one of the fastening staples.

It will be understood that the invention is for the construction of acollapsible box member, and that therefore either the body portion ofthe box or the top member may be used interchangeably with itscomplementary part even if of different construc- "OLLAPSIBLE FLEXIBLEBOX.

tion, but it is desirable that both portions.

be constructed in thesame way, and in the drawings therefore the coveror top is shown constructed the same as the body portion of the boxexcepting that it isformed from a blank. the area of which between thescored lines is slightly greater than that of the body portion in orderthat the top may fit thereover: In the description for brevity i simplyrefer to the body portion of the 1 designates the base, 2 the sidewalls, and 3 the end walls. The side walls 2 are separated from the baseby the longitudi nal scoring 4 and the end walls are similarly separatedby the transverse scoring 5, and where these lines of scoring intersectthere is formed the corner ortions diagonally scored as at'fi to provi efor an internal fold when the box is turned up. These corner portionsform triangular portions 8 and 9 which register when the box is in itsturned up position.

To further describe the invention I will now refer to the blank after'ithas been first folded.

Taking the blank as shown in Fig. 4, the side walls 2, in conjunctionwith the. sections 8 and 9, are-bent inwardly along the scoring lines 4,and are folded flateon the bottom 1 of the box. The triangular portions8 may then be securely aflixed to the end walls 3 by means of thestaples 1G, and similarly the pointed ends of the fastening clips 11 arepassed through the end body portion of the box member and'the sametriangular sections, as illustrated in Fig. 2. The clips 11 consist of abody portion having pointed ends bent at right-angles and are alsoprovided with projecting.

tongues 12. v

The foregoing paragraph describes the normal position of the knockdownbox. When the box is to be folded up the walls 2 are bent outwardly andthe end walls 3 are bent inwardly, so that the walls assume a verticalposition, as. shown in Fig. 2, with the adjacent faces of the triangularportions 8 and 9 lying against each other. In this position the pointedends of the staples 11 lie hidden when the box member is struck up, andthe projecting. tongues are bent over the portion of the box to whichthe staple is secured and also over both walls of the triangularsections 9 of the folds, the

side walls being thereby secur 1y aflixed to the end walls, allas shownin 1g. 3. What I claim is A collapsible flexible box, formed from a flatintegral blankscored transversely and longitudinally to supply turned upside and end walls; said Walls joined with an mtegral internal fold ateach corner of said box member; each of said folds consisting of a pairof substantially triangular por tions having bases flush with the eripheral edge of thebox member, means ocated on the outside of said box,passing through one of its walls and through one of said triangularportions, and fixedly securing the latter to the former and comprising amember for detachably securing the correspondv to be bent over the bodyportion of the box member, and also over the base edges of saidtriangular portionsfor securely holda ing the sad corner folds together,substantially as d scribed.

In testimony whereof, I aflix my signa ture, in presence of'twowitnesses.
